One of the test cases added by this commit has not been very
stable in the buildfarm. Latest example is here:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=prion&dt=2024-02-01%2021%3A28%3A04
and I've seen similar failures intermittently on other machines.
I'd suggest building this test atop a table that is more stable
than pg_class. You're just waving a red flag in front of a bull
if you expect stable statistics from that during a regression run.
Nor do I see any particular reason for pg_class to be especially
suited to the test.
